1. How to wear hearing aids?
When using hearing aids for the first time, you may feel that the sound is not real and clear enough. Because you have become accustomed to the original hearing situation, when you use hearing aids, you hear some unfamiliar sounds, so you can't adapt to it for a while. The main way to solve the problem is to carry out the necessary adaptability training. Don't wear it for too long at the beginning, don't use too much volume, and adapt slowly.
2. How to perform adaptive training?
Hearing aid adaptability training is not complicated. The general principle is to insist on wearing it and adapt step by step:
(1) In terms of daily wearing time, it should be from short to long;
(2) From the perspective of volume adjustment, it should be small first and then large;
(3) From the perspective of the communicative environment, it is better to be quiet first, then mixed, simple first and then complicated.
Such a gradual and orderly progress will enable you to get through the adaptation period as soon as possible and maximize the role of hearing aid.
3.Why do hearing aids produce howling?
The contact part of the earplug and the ear canal is not tightly sealed, and the amplified sound leaks from the gap and returns to the microphone to be amplified again. Howling will occur. This phenomenon is similar to our common whistling sound when the microphone is close to the speaker.
(1) The hand or an object is close to the hearing aid, because part of the sound is reflected on the palm or object and then returned to the microphone for further amplification.
(2) The hearing aid is not completely inserted into the ear canal or is not tightly sealed with the ear canal wall, and the amplified sound is leaked and transmitted back to the microphone.
(3) There is a large amount of earwax in the ear, and an earwax embolism occurs. The amplified sound is reflected on the earwax and transmitted to the microphone again, which will also generate feedback.
4. How to avoid howling?
(1) First turn the hearing aid volume adjustment knob to the \1\ position, then insert the earplugs into the ear and try to plug them as tightly as possible, and then adjust the volume to the clearest position.
(2) If the earplugs cannot be plugged tightly, please try another more suitable earplug, plug the ears tightly, and do not leak air.
